Lesson 2.1: The Basics of Adding & Subtracting Fractions
This teacher-led small-group activity includes a printable math mat (with space for modeling & written work) and 12 editable task cards for hands-on practice.
Students will:
• build fraction models to add and subtract fractions
• determine when fractions need a common denominator
• apply benchmarking, partitioning, and equivalence to support their models
• represent addition & subtraction on number lines and area models
• justify whether fractions can be added or subtracted in their given form
• simplify sums and differences when possible
